Well, I'm gladly presenting the pictures of ever first EuroVan running a 220A alternator
Today I have received INA F-232001 and INA F-557311 pulleys and was playing with them. While both can be shimmed to correct offset, I didn't like how they thread on Valeo alternator - it looks like rotor's shaft on alternators used on MB vehicles might be using longer threads and installing these pulleys on Valeo alternator with proper shims to match offset of AXK pulley is leaving only about 5-6 mm of thread exposed for MB pulley to grip on. So disliking it, I followed Itsamoto's advise to try a non-clutch pulley from stock Bosch alternator. And it works!
Proper spacing - no need to add any shims and it grips right on (the same nut and washer from Bosch alternator were used). Valeo 220A alternator gets excited on EuroVan's idle RPMs and produces 14.3V!
I'm gonna do some review with lots of pictures and my wiring schematics, but being busy at work it might take for me a few weeks...
Basically, it boils down to sourcing a 220A Valeo alternator from 2010-2014 VR6 3.6L Touareg and putting a pulley from stock Bosch alternator on it. Very easy upgrade. No messing around with alternator mount brackets or spacing alternator out to remove belt slack.
Saddle mount is exactly the same as on stock Bosch unit. No changes to exciter circuit. Valeo alternator uses the same connector for exciter wire (on my photo you can see some extra wires, but I had to solder them because the voltage regulator on this alternator had it's socket broken off). Very easy swap and direct bolt-on replacement for EuroVan. It looks like my high-output alternator quest is finally over
